To all whom it may concern:

Be it known that I, GEORGE FRANKLIN WEN'rz, a citizen of the UnitedStates, residing at St. Louis, State of Missouri, have invented a newand useful Distilling Apparatus, of which the following is a specifica-tion.

The present invention relates to means for obtaining pure water; and theobject is to provide a'structure wherein the heat eliminated .from thesteam in the condensing operation is conserved.

It is also the object to provide a novel and simple means for aeratingthe distilled water,

the air being first purified and the amount thereof boing regulable asdesired. Further than this, it is thelaim to provide apparatus that canbe employed for domestic or house# hold use, the usual stand-boilerforming a part thereof.

The preferred embodiment of the invention is illustrated in theaccompanying drawings, wherein- Figure 1 is a side elevation of theimproved apparatus, portions thereof being shown in section. Fig. 2 is avertical sectional view, on an enlarged scale, through the condenser andthe air-mixer. Fig. 3 is a vertical sectional view through thesteam-generator.

Similar numerals of'reference denote corresponding parts in all thefigures of the drawings.

The steam-generator is designated as a whole by the reference-numeral 10and is shown in Fig. 1 placed upon an ordinary range 11, though a gas orother heater can be employed, if desired. The construction of thegenerator will be more clearly seen in Fig. 3. It comprises a receptacle12 havinga conical top 13 and a bottom 14, the lower corners beingpreferably rounded, as shown at 15. This receptacle can be placed, ifdesired, within a jacket (shown at 16) which is larger than the same inorder to provide an annular heating space or flue 17 between the twowalls, theupper end of this jacket being tapered, as shown at 18, andterminating at the upper end of the receptacle to permit a free draftthrough said flue. The receptacle is preferably` verticallyadjustablewithin the jacket, beingsupported upon brackets 19secured tothe inner walls of saidr jacket by l n meansofbolts 20, that passthrough slots 2 1,

formed in the brackets. The receptacle may carry an exposed gage-glass22, the connections of which pass through slots '23, formed in the wallof the jacket. It will be understood, however, thatthe jacket may bedispensed with, if desired.

A condenserA 24 constitutes a part of the apparatus and consists of acylindrical watertight casing 25,v within which is located aA worm 26,the upper end of which ro'ects from the u per end of the casing in t eorm of a nipp e 27, the lower n end extending through the lower ortionof the casing, as shown at 28, and having a depending discharge-pipe v294attached thereto, saidv pipe projecting into the receiver 30 for thedistilled water. Block-tin has been found to be excellent material foruse in the construction ofthe coil, though the invention is not limitedin this respect. The generator and condenser are connected by asteam-pipe 31, attached to the a ex of the receptacle 12 by means of acoup ing 32.f' This pipe is preferably constructed of block-tin or othermetal that can be readily bent so as to permit the generator being movedabout -as may be found necessary. Arranged in this pipe is anair-injector, (designated as a whole by the reference-numeral 33.) Theconstruction of the mixer is illustrated in Fig. 2. It comrises an outershell 34, having a tapering ore, within which is arranged a nozzle 35,connected with the steam-pipe. This nozzle. is adjustable toward -andfrom the tapered end of the bore, and for this purpose it is threaded inthelarger end, a jam-nut 35a vbeing employed for normally holding theparts against relative movement. The shell 34 carries an upstandingnipple 36 upon the upper end of which is screwed an air-regulating head37, having an annular series of inletorifices 38, which are located atdifferent distances from the end of the cap. Forming a art of this c-apis a strainer comprising a ase-plate 39, which is secured to the-cap andto which are fastened, by means of suitable clips 40, spaced perforatewalls 41, formed of wire fabric and holding between them a lin- Patentedoct. 16, 1906. i

ing or filling 42, preferably composed of 'cotton.

The condenser 24 is located alongside a rescondenser from the boiler bymeans of a ycoup-y ling-pipe 44, connected tothe lower portion of theboiler andthe casing-25.* An'outletf conduit 45 extends from the top ofthe casing 25 to the top of the boiler, being designed t0 IIC carry'offthe heated Water, and thus/permit the inflow of cold water from thebottom of the boiler, as will be readily unde tood. vAsediment-discharge nipple 46 ay also be connected to the bottom of ecasing 25. Water is supplied to the s am-generator through a pipe 47,which is preferably constructed of.' flexible material and is connectedwith the upper portion of the boiler 43 and the lower portion of thereceptacle 12, passing through a slot 48;.in the jacket and having anexposed valve 49 to control the passage of water.

Assuming the boiler and condenser filled with water and the generatorpartially filled, it will be evident that fire in the stovewill producesteam in the generator, which will flow through the 31 and dischargingthrough the nozzle 3 5 will cause an inflow of' air into the mixer, saidair being purified,

how-ever, by passing through the cleaning de vice above described. Themixed steam and air will thus enter the worm, and/coming into contactwith the cold Walls thereof the steam will be condensed, and the waterwill flow into the receiver 30, carrying the air with it, which air willbubble up through the water therein, thus insuring thorou h aeration ofthe latter. The amount of alradmitted to the mixer'is of courseregulable by screwing the cap 37 up or down upon thenipple, therebysuccessively uncovering or covering the openings. The force with whichthe air is entrained is due to the particular arrangement of thedischarge end of the nozzle in the contracted end of the shell.Experiments have shown that when the discharge end of theshellf is madelarge as compared to that of the nozzle the air will not be carried asdeeply into. the Water in the receiver. With vsmall orifices, as shown,and with the end of the nozzle fitted closely in the shell the airv willbe carried through the discharge-pipe when there is a large body ofwater in the receiver. As the water in the condenser becomes heated fromcontact with the coil it rise through the pi '45. and enter the top ofthe boi'er, its sie being taken by cold water passing t ou h the pipe44. Thus the Water in saidl boi-er will gradually be made hot by theheat abstracted from the steam that is condensed. When a new supply ofwater is required the condenser, it is drawn from the top of' the boilerthrough the pipe 47, and thus this heated Water 1s ernplo ed.' As aresult the heat is conserved and7 used over a ain. The boiler may ofcourse be used in t ordinary manner by being connected with thedistributing system in the house and it may also. be connected totheWater-back ofthe stovethese various connections not being shown,however, as they do not enter into. the osent invention. Because of its.adjustab e connection with the jacket the receptacle 112 can be raiseder lowered, as desired, and thus placed at diiferent distances from thefire.v

By means of this apparatus it will be a parent that pure water may beobtaine and that it is thoroughl aerated by air which has been deprivedof ust and unclean matter. The adjustment of the nozzle and the relating means for admission of the air are 1mrtant factors in theperformance of these unctions. The heat withdrawn from the steam duringthe condensing operation is not wasted, as the water absorbing the samecan be employed not only for domestic purposes, but for supplying thegenerator. The apparatus is especially designed for househol use and canbe readily understood and operated by ersons other than experts in thisart.

Fprom the foregoing it is thought that the construction, operation, andmany advantages of the herein-described invention will be a parent tothose skilled in the art withoutI urther description, and it will beunderstood that various changes in the size, shape,

proportion, and mino-r details of constructlon may be resorted towithout de arti-ng from the spirit or 'sacrificing any of) theadvantages of the invention.
